Application filed July 19, 1916. Serial No. 110,164.

To all whom it may concern.-

lte it known that I, Am 0. Inwm, a eitizen of the United States,residing at Fort Mills, Philippine Islands, have invented eertain newand useful Improvements in Ball and Roller Bearings for dournaldtoxes;and 1 do hereby declare the following to be a full, clear, and exactdescription of the in vention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to journal bearings for axles or shafts and thelike and more particularly to devices employing rollers and balls, orsimilar anti-friction devices an ranged in a boxing or the lilie aroundand at the end of the axle or shaft to take up direct friction from theaxle or shaft and to q'esist end, thrust, obviating the objection ofheretofore proposed bearings, where the rollers rotate on their axesmuch faster than the axle or shaftQ An object ofthis invention is toprovide rollers with large and small diameters, the

smaller diameter of the rollers to engage the =surfuees rovieled on theinside of the boxing and t ie larger diameter of the rollers to engagethe bearing surface of the axle or shaft, has reducing the speed of therollers around the inside of the boxing.

Another object of this invention is to pro vide guide rings to {itloosely over the smaller diameter and at each end of the rollers tocause said rollers to move in unison.

A n'it her of this invention .is to pore i. ne 3 rollers and balls theln atoll times and whereby hr ieii ti-i'ig material {may be drained. Astilgl' iiiii her ob'eet of this in'gention is to pron'itjle and i'ollerbearings for journag boxes of the hove stated character,

wineh shull bei mple, durable and efficient, anglwhlqli n ay Lbeinanufaetured and sold at a eo ngaratfivly low cost.

and other objects in view as wil beegr'ne more alfi'perent as' thedescription prooeeds, he invention consists in cer-v oininqo nationerrangerhent of arts as will eseribed and a r. i e gilggi aeorngleteunderstanding of my i11 vol t on, noeis to be held it the'fllowgggvgfiseription turd aceompanying drawing,

The casing 7 projects beyond the outer end of the axle or shaft 1 asclearly illustrated in Fig. l'to receive a circular enlargement 22formed on the inner face of the head 8, which has formed thereon anunnular groove forming a portion qt a race way to receive ball bearings:23. An unnuhir shoulder 24 is formed on the inner face of theenlargement 22 for an engagement with the ball bearings 23; The shoulder24 has an annular groove which forms a portion of a lubricating groovefor lubricatin the ball bearings 23. The head 8 is provided with acircular recess 26 in the center thereof, which is provided with itswalls screw-threaded to receive a screw-threaded retaining'ring 27,having an annular flange 28 formodthereon, which is grooved to form theremaining portion of the lubricating re 25, andis further provided withan inclined face 28 to engage the other side of .theball bearings 23..It will he noted that of the casing 7 is provided with a downwardlyinclined roove or channel 31, having branches which communicate with theonnular grooves 15 and having an opening 32 communicating with itslowermost end which is screw-threaded to receive a plug whereby thelubricant within the'cnsing 7 may be drained therefrom. A suitablegasket 34 is positioned between the head 8 and the casing 7 to provide adust and liquid proof connection. n

From the foregoing description taken in.

connection with the accompanying drawing. it will he noted llmt theraising 4 normally turns or rotates with the axle or shaft 1, but it'the rollers become nnserviceulde and refuse to rotate. the casing 4remains stationary and tlu axle or shaft 1 is free to rolatc within theBabbitt bearing 5, preventing injury to the casing l or the rollers.

While I have shown and described the preferred omlmdiment of myinvention, it will he understood that minor changes in construction.combination and arrangement of parts may he made without departing fromthe spirit and scope of the invention as claimed.

lluving tluls described my iurentiomwhat 1 claim is:-

l. A device of the character set forth comprising a shaft. a casingthereon, a Babbitt bearing positioned between the casing and the slm ft.a casing surrounding the first mentioned casing, a head detuchuldysecured to the second mentioned casing. said second mentioned casingprovided with annular grooves providing hearings therebetween, rollersconsisting of large and small bearing members positioned withintlie'secoud mentioned casing, said small bearing members resting upon.the bearings within the second mentioned casing, and said large bearingmembers located \vlthin the annular grooves and bearing upon the firstmentioned casing, hnd means carried by the first mentioned casing forcausing the rollers to rotate in unison.

2. A device of the character set forth comprising an axle, a casingsurrounding said axle and spaced therefrom, inwardly directed lugsformed on said casing, Babbitt material molded in said-casing betweenthe casing and the axle and retained in said casing by the lugs, aboxing surrounding the casing, and rollers journaled in said boxing andbearing nponsaid casing to rotutably support the boxing.

In testimony whereof Iallix my signature.
